[jira] [Updated] (FLINK-5892) Recover job state at the granularity of operator

     [ https://issues.apache.org/jira/browse/FLINK-5892?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

MaGuowei updated FLINK-5892:
----------------------------
    Description: 
JobGraph has no `Operator` info so `ExecutionGraph` can only recovery at the granularity of task.
This leads to the result that the operator of the job may not recover the state from a save point even if the save point has the state of operator.
